EL-CELL proudly presents the new ECD-nano electrochemical dilatomete ith a resolution in the true nanometer range. This new development is full ompatible with the ECD-1, except for the sensor/load unit. With the ECD- he electrode displacement is measured with an LVDT-sensor, while the ne CD-nano utilizes a capacitive parallel-plate sensor system. Still, with it arge-range LVDT sensor, the ECD-1 is the right choice for test specimen ith overall dimensional changes in the range of 5 to 500 micrometers. A he distinct advantage, the new ECD-nano provides a much better resolutio elow 5 nanometers (against 50 nm for the ECD-1).
We believe the high resolution of the ECD-nano will open new areas o pplication to electrochemical dilatometry. For instance, quasi 2-dimensiona lectrode processes like the SEI formation in lithium-ion batteries, or th lectrochemically driven growth of passivation layers on metal surface ight become the subject of future dilatometric studies.
